PATENT OFFIeE,

HYDROCARBON-FURNACE.

SPECIFICATION forming part of Letters Patent No. 279,904, dated June 26, 1883.

.act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of vaporgenerators in which liquid hydrocarbons are vaporized by means of steam, and to furnaces in which hydrocarbons in a vaporous form are burned; and the nature of my invention consists incertain improvements in the construction of such generators and furnaces, as

hereinafter described and shown.

In the accompanying drawings, in which corresponding parts are designated by the same letters, Figure 1 is a view partially in section of a vapor generator and furnace having my improvements applied thereto. Fig. 2 is a perspective view illustrating the arrangement of the pipes in which the air and also the steam areheated by the outgoing products of coinbustion from the furnace.

In the drawings, H designates the cylindrical chamber in which the vapor tiS generated, which is surrounded by an annular steamspace, B, which communicates by means of the pipe or with a coil of pipe, A, arranged within a receptacle, W, which coil is connected by the pipe p with the steam-supply. This cylindrieal chamb H has within it a steam-space, O, which com unicates with the steam-j acket B. The steam admittedthrough the pipe at is regulated by a valve, 44, and flows downward to the bottom of the 'stamjacket B, heating the exterior of the generating-chamber H in its passage, from whence it rises through the interior of the steam-space O to the pipe E,

which conducts it into the bottom of the gener= the pipe V will drop downward from one re-' ceivcr to another in a graduated manner. The

pipe M. The steam made use of for vapor- 6o izing the hydrocarbons is generated in a boiler, N, which is heated by theescaping products of combustion from the furnace. The boiler is arranged in a receptacle or flue-space, X,

above the combustion-chamber of the furnace, 6 5 and the pipe Teaching from the boiler to the vapor-generator is doubled or coiled on each side thereof, as shown at b, so as to present as much surface as possible to the es- A series of air-pipes, W, are also arranged within therecaping products of combustion.

ceptacle or flue-space X, for the purpose of utilizing the heat of the escaping products of combustion from the furnace for heating the The incoming air, which unites with the gas from the generator in the 1nixing chan1ber O. The air is forced by means of the blower Z into the box 1?, from whence it is distributed by a series of pipes, WV, in such a manner as to absorb the heat from the escaping hot gases. thus heated is collected in the receiver X, from whence it is conducted by the pipe I "to. the mixingchamber O. The flow of air and gas into the mixing-chamber through the pipes I and K, respectively, may be accurately ad- 85 justed by means of valves at V and U or other proper points upon the said air and gas pipes. At the base of the generator is a furnace, S,. from whence the products of combustion, rising, expand into the space WV through perfora- 0 tions in the wall, and finally pass off through a smoke-pipe.

The operation of the apparatus is as follows: The requisite amount of steam is admitted,

which flows through the coil A and pipe a to 5 the annular steam-space B on the outside of the generator, from whence it flows upward through the interior steam-space, c, and pipe E to the bottom of the generating-chamber H,

The air where it comes in contact with the liquid hy- I00 droearbon, which enters through the pipe Y and flows downward over the outer surface of the spheroidal receivers 1, 2, 3, 4, and 5. The liquid hydrocarbon flows over the edge of the upper receiver, 1, and drops upon the outer edge of the receiver 2, from whence it drops successively to the receivers 3, 4, and 5. In other words, the outer edges of the receivers successively intercept the liquid in its downward progress and spread it outward to meet the ascending steam. By causing the receivers 1, 2, 3, 4, and 5 to gradually increase in size from top to bottom, a very thorough intermixture of the steam and liquid is efl'ected, and this intermixture is rendered still more perfeet by the circular deflector J, which is attached to the walls of the generator H in such a manner as to cause the gas generated in the said generator to be deflected outward over the exterior edges of the deflector before passing into the eduetion pipe K. The steam should flow through the chamber H under suf ficient pressure to carry the hydrocarbons in vaporous form through the pipe Kto the mixing-chamber 0, where they meet the air entering through the pipe V, and are thoroughly intermixed therewith. The inflammable mixture from the mixing-chamber O is ignited and performs its work in the furnace 0, from whence the spent gases and products of combustion are carried by the draft upward to the flue-space or receptacle, in which are arranged the boiler, steam-pipes, and air-heating pipes. The air thus heated flows downward through the pipeV to the point where it is mixed with the vapor from the generator, and thus raises the temperature in the furnace 0 to ahigh degree, and produces a flame adapted to metallurgical operations requiring an intense heat.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination of a furnace in which the incoming air to support combustion and the steam for vaporizing liquid hydrocarbons are heated by the spent gases and products of combustionv with the described apparatus for generating vapor from liquid hydrocarbons, as and for the purposes described.

2. In the apparatus for generating vapor from liquid hydrocarbons herein described, the generating-chamber having an internal steam-space consisting of spheroidal receivers increasing in size from top to bottom, as and for the purposes described.

3. The combination of the spheroidal receivers of gradually increasing size, thepipe through which the steam enters the generating-chamber, and the oil-supply pipe, as and for the purposes described.

4. In the apparatus for generating vapor JOHN B. ARCHER.
